Input Channels

5. Input Channels

5.1 Brief Technical Overview

Referring to the illustration below, each input channel of the DN9848E processes the audio signal through delay and gain stages, followed by 12 bands of parametric

equalisation, and a full-band compressor. All key stages are monitored for signal clipping which, if detected, illuminates the top red segment at the top of the input

signal meter; thus, clipping of the signal during processing is not inadvertently missed. In addition, the signal level is monitored at the compressor to provide signal

headroom and gain reduction indications at the meter.

5.2 Setting Input Parameters

5.2.1 The Input Menu

The signal processing for each input channel is programmed independently via

the separate Input menu associated with each channel. The signal processing

parameters are described below in menu order.

• • To access the Input menu pages for a particular channel

1. Press its blue MENU ACCESS button (A – D) to switch to its menu.

2. Press the button repeatedly to step through the pages in turn.

Notethat, after the last page, the next button press will cycle the menu

back to the rst page.

• • To skip across to the same parameter on another input, press its

MENU ACCESS button.

5.2.2 Naming the Input Channel (Page 1)

Each input channel can be allocated a name up to seven characters long, which

will be shown in the rst page of the menu for easy reference. The default names

are “Input A”, “Input B”, etc. Names are retained after power down and are

included in stored settings.

• • To enter a name

1. Turn the left DATA ENTRY control knob clockwise to access the Input

Name sub-menu page.

2. Use the centre control knob to move the cursor right or left, and the

right control knob to select the letter, number or symbol.

3. On completion, turn the left control knob anti-clockwise to go back

to the main page. The new name is now shown to the left of the

menupage.

5.2.3 Gain and Delay (Page 1)

Gain and delay are also set in the rst page of the channel’s menu, providing

easy access for quick adjustment during set up or performance. Note that the

delay can be specied in terms of time or distance, as preferred. The unit of

measurement is changed in the Set Up menu (see Section 7.9).

• • To set the delay

• • Turn the centre DATA ENTRY control knob slowly for step increments,

or sharply to leap to the bottom/top of the range (two or three sharp

turns should cover the whole range). When the delay is set for time the

overall range is 0 to 1.00s, with steps of approximately 20.8μs between

0 to 1ms and steps of 0.02ms between 1ms to 1s. When the delay is set

for metres, the overall range is 0 to 343.53 m in steps of 0.1 m and for

imperial (feet and inches) the overall range is 0’ 0” to 1127’ 0” in steps

of 1”.

• • To adjust the gain

• • Turn the right DATA ENTRY control knob. The range is –40 dB to +12 dB

in steps of 0.1 dB, with an OFF position just ‘below’ –40 dB. Setting the

gain to OFF will mute the input signal.

User dened channel name

Delays can be set in seconds, metres or feet and inches

10 DN9848E User Manual

5.2.4 Parametric Equalisation (Pages 2 to 13)

The DN9848E provides 12 parametric equalisation stages on each input channel,

for equalising the input signal in respect of room/venue characteristics.

Each stage can be used across the full range from 20Hz to 20kHz and is set

independently via its own menu page.

• • To set a PEQ

1. Set a centre frequency (21 steps per octave) and bandwidth (0.08 to

3Oct) for the PEQ section, using the left and centre DATA ENTRY control

knobs, respectively.

2. Turn the right control knob to set an attention/boost level in the range

-18 dB to +6 dB.

PEQ sections that are not needed in the set up should be set to 0 dB attention

/ boost.

5.2.5 Compression (Page 14)

Each input has an independent full-range compressor to improve the dynamics of

the incoming signal levels. The compressors are variable ratio and can be set to a

hard knee characteristic for a sharp gain reduction response at the compression

threshold, or soft knee for a more ‘musical’ response.

• • To set the compressor parameters

1. On the rst compressor menu page, use the centre DATA ENTRY control

knob to select a threshold value in the range –10 dBu to +21 dBu, and

the right control knob to set a ratio from 1:1 to 5:1.

2. Turn the left control knob clockwise to access the rst sub-menu page.

Use the centre control knob to select a hard or soft knee characteristic

and the right control knob to set the bypass state to ‘No’ so that the

compressor is included in the signal path.

3. Turn the left control knob clockwise to access the second sub-menu

page. Use the centre control knob to set the compressor attack time

(range of 40μs – 1ms in 20μs steps or 1ms to 100ms in 1ms steps). Use

the right control knob to set the release time (10ms to 2s in 10ms steps).

• • To switch the compressor out of the circuit

• • Set the bypass state on the second compressor page to ‘Yes’. The other

settings are held for future use.

5.3 Monitoring the Input Signal

Each of the four inputs has a nine-segment signal

meter for monitoring the internal signal clipping and

compressor headroom or gain reduction.

The top CLIP segment (shown illuminated in diagram

left) monitors the internal signal clipping. It operates

independently of the rest of the meter, illuminating

when signal clipping is detected at any stage in the

processing circuits, regardless of whether the input

level is above or below the compressor threshold.

Hence, the audio engineer has full visibility of internal

signal clipping that may result in audio distortion.

The 0 dB to –40 dB signal meter monitors the input level on a relative scale,

where the “0” segment is set at the specied compressor threshold. For example,

if the threshold is set to +9 dBu then the input signal meter “0” segment is set at

9 dBu true value, and a signal of –3 dBu registers as 12 dBu below the threshold

(below left). Thus, when the signal level is below the threshold, the meter

indicates the headroom.

When the signal level reaches the threshold, that is, the red “0” segment

illuminates, the meter ‘ips’ and reads downwards to show the amount of gain

reduction applied to the signal.

Output Channels

6. Output Channels

6.1 Brief Technical Overview

The output channels are slightly more complex than the input channels in that they are responsible for the signal routing as well as output signal processing. At the

input of each output there is a matrix mixer (see following diagram) that can source each output from a mix of the four input channels (A to D). An output can derive its

source from a single input by setting the gain of the other inputs to o. The amount, or level, of input that can be routed to the output is variable from –40 dB to 0 dB

in 0.1 dB steps, or can be switched o completely.

Matrix Mixer

After routing, the resultant signal is passed through the various output processing circuits as shown below. Processing options include delay, inversion,

twoindependent phase adjustment stages (Phase Shift and All Pass), ltering, six stages of parametric equalisation, gain/mute, compression and limiting. All key

stages are monitored for signal clipping which, if detected, illuminates the top red segment at the top of the output signal meter. In addition, the signal is monitored

through the compressor and limiter stages to provide headroom/gain reduction indications at the signal meter.

12 DN9848E User Manual

6.2 Setting Output Parameters

Signal processing for each output channel is programmed independently via

the separate Output menu associated with each channel. The signal processing

parameters are described below in menu order.

• • To access the Output menu pages for a particular channel

• • Press its blue MENU ACCESS button (1 – 8) to switch to its menu.

• • Press the button repeatedly to step through the pages in turn. Note

that, after the last page, the next button press will cycle the menu back

to the rst page.

• • To skip across to the same parameter on another output, press its

MENU ACCESS button.

6.2.1 Naming the Output Channel and Matrix Mixing

(Page 1)

Each output channel can be allocated a name up to eight characters long, which

will be shown in the rst page of the menu for easy reference. The default names

are “Output 1”, “Output 2”, etc. Names are retained after power down and are

included in stored settings.

Each output of the DN9848E can be sourced from a mix of the input channels.

Thelevel of the source inputs can be set to between 0.0 dB and –40.0 dB or

switched o.

• • To enter a name

1. Turn the left DATA ENTRY control knob clockwise to access the

OutputName menu page.

2. Use the centre control knob to move the cursor right or left, and the

right control knob to select the letter, number or symbol.

3. On completion, turn the left control knob anti-clockwise to go back

to the main page. The new name is now shown to the left of the

menupage.

• • To set the source input channel and adjust the level

1. Using the centre DATA ENTRY control knob, select source input channel,

that is, A, B C or D.

2. Turn the right control knob to select the level of the source input,

orswitch level o.

3. On completion, press the next output channel MENU ACCESS button to

go to the next menu page.

6.2.2 Signal Invert, Delay and Output Level (Page 2)

Each output can be phase inverted by 180º (separate to the phase-alignment for

crossover), delayed for system alignment and the level attenuated or boosted.

Delay can be specied in terms of time or distance, as preferred. The unit of

measurement is changed in the Set Up menu (see Section 7.9).

The Level entered here sets the baseline output level, that is, the ‘zero’ value,

for the rotary Output Gain controls. For example, if the Level is set to 6 dB, the 0

represents 6 dB. Turning the rotary Gain Control right/left will increase/decrease

the level in a proportional manner beyond 6 dB (it is not directly additive since

the gain is limited to +12 dB). Hence, the Output Gain controls enable ne-tuning

during a performance, while the baseline output level is retained as a standard

setting for future use.

• • To invert the output signal

• • Turn the left DATA ENTRY control knob clockwise until the Invert eld

reads “Yes”. The default setting is “No” inversion.

• • To set the delay

• • Turn the centre DATA ENTRY control knob slowly for step increments,

orsharply to leap to the bottom/top of the range (one or two sharp

turns should cover the whole range). When the delay is set for time

the overall range is 0 to 300.00 ms, with steps of approximately 5.2μs

6.2.3 Phase Adjustment (Pages 3 and 4)

To meet the demands of a wide range of situations, the Klark Teknik DN9848E

provides two all-pass lters with complementary control parameters for

ne-tuning the phase response on each output, for example, for alignment

at crossover. The rst lter is presented as a ‘phase shifter’ for which you can

set a specic phase shift at a reference frequency, for example, the HPF or LPF

(typically the crossover point). The second lter enables a 1st or 2nd order phase

shift to be applied at a chosen frequency. With 2nd order, the phase shift window

can be shaped, that is, you can adjust the steepness of the transition by setting

the Q value.

For detailed information on how these lters modify the signal, please refer to

Section 10 “Application Notes”.

• • To set a precise phase shift at a reference frequency

1. Step to the Phase Angle/Ref page shown right.

2. Turn the centre DATA ENTRY control knob to select a phase angle

between 0º and 180º. Turn the right control knob to set the reference

frequency to HPF, LPF or one of the six PEQs (set in the subsequent

Output menu pages).

• • To apply a 1st order phase adjustment in relation to a chosen

frequency

1. Step to the All-Pass page, shown right.

2. Turn the right DATA ENTRY control knob to enable a 1st (90º)

ordershift.

3. Turn the left control knob to the required frequency.

• • To apply a ‘shaped’ phase transition at a chosen frequency

1. Step to the All-Pass page, shown right.

2. Turn the right DATA ENTRY control knob to enable a 2nd (180º)

ordershift.

3. Turn the centre control knob to select the Q (slope) and the left control

knob to select the frequency.

6.2.4 High Pass and Low Pass Filters (Pages 5 and 6)

The DN9848E provides the following high and low pass lter (HPF and LPF)

options for crossover purposes:

Butterworth: 6, 12, 18, 24, 36 and 48 dB / Octave

Bessel: 12, 18, 24, 36 and 48 dB / Octave

Linkwitz Riley: 12 and 24 dB / Octave

Peaking (HPF only): 12 and 24 dB / Octave 0-6 dB Gain

Bypass: No Filter

• • To add a high/low pass lter to output processing

1. Step to the HPF or LPF page, as required (see right).

2. Use the left DATA ENTRY control knob to specify the cut-o frequency.

3. Use the centre control knob to select the lter type and the right control

knob to set the slope/gain. (The right parameter switches between

slope and gain, dependent on the lter type).

• • To bypass the high/low pass lter processing

1. Step to the HPF or LPF page, as required.

2. Turn the centre DATA ENTRY control knob anti-clockwise to ‘Bypass’.

The last selected values for each type of lter are retained in the

background for easy recall.

6.2.5 Parametric Equalisation (Pages 7 to 12)

The DN9848E provides six parametric equalisation stages on each output

channel, for equalising the output signal in respect of loudspeaker and/or

system characteristics. The rst and last of these PEQ sections can, alternatively,

becongured for lower and upper shelving equalisation. All the PEQ sections can

be used across the full range from 20Hz to 20kHz and are set independently via

their own menu page.

• • To set a PEQ

1. Set a centre frequency (21 steps per octave) and bandwidth (0.08 to

3Oct) for the PEQ section, using the left and centre DATA ENTRY control

knobs, respectively.

Or:

Switch to an LEQ/HEQ setting with a 6 dB or 12 db slope by turning the

centre control knob clockwise beyond 3 Oct (see below). Use the left

control knob to set the LEQ/HEQ frequency.

2. Turn the right control knob to set the amount of attenuation/boost from

-12 dB and +12 dB.

If a PEQ section is not needed in the set up, set its level to 0 dB.

Any PEQ can be used as the reference frequency for

the Phase Shifter (see Section 6.2.4)

14 DN9848E User Manual

6.2.6 Compression (Page 13)

Each output has an independent full range compressor to improve the audio

dynamics and/or reduce louder signal levels to avoid loudspeaker damage.

Thecompressors are variable ratio and can be set to a hard knee characteristic

fora sharp gain reduction response at the compression threshold, or soft knee for

a more ‘musical’ response.

• • To set the compressor parameters

1. On the rst compressor menu page, use the centre DATA ENTRY control

knob to select a threshold value in the range –10 dBu to +21 dBu,

andthe right control knob to set a ratio from 1:1 to 5:1.

2. Turn the left control knob clockwise to access the rst submenu page.

Use the centre control knob to select a hard or soft knee characteristic

and the right control knob to set the bypass state to “No” so that the

compressor is included in the signal path. The relative position of the

compressor threshold to the limiter threshold will be indicated by an

illuminated segment at the meter (provided the compressor threshold is

below the limiter threshold).

3. Turn the left control knob clockwise to access the second sub-menu

page. Use the centre control knob to set the compressor attack time

(range of 40μs – 1ms in 20μs steps or 1ms to 100ms in 1ms steps).

Usethe right control knob to set the release time (10 ms to 2 s in

10mssteps).

Illuminated segment

shows the compressor

position relative to the

limiter threshold

• • To switch the compressor out of the circuit

• • Set the bypass state on the second page to “Yes”. The other settings will

be retained for future use.

6.2.7 Output Limiter (Page 14)

In addition to compression, each DN9848E output has a limiter to protect any

attached equipment being driven into clip and potentially being damaged.

Notably, the DN9848E uses a special ‘look-ahead’ limiter so that it can anticipate

transient overshoots and act ‘immediately’ (see Section 10 “Application Notes”

for further details). The limiter threshold can be adjusted to accommodate the

varying requirements of commercial equipment.

• • To set the limiter parameters

1. Select a threshold value in the range –10 dBu to +21 dBu with the left

DATA ENTRY control knob.

2. Use the centre control knob to set a release time between 1ms

and100ms.

3. Use the right control knob to select a hard or soft knee characteristic for

a sharp or gradual cut-o, respectively.

• • To switch the limiter out of the circuit

• • Turn the left DATA ENTRY control knob fully clockwise until the

threshold value reads ‘OFF’ (a sharp turn will leap to the OFF position).

15 DN9848E User Manual

6.3 Monitoring the Output Signal

Each of the eight outputs has an 11-segment signal meter for monitoring internal signal clipping and output levels that may cause damage to the

loudspeaker equipment.

The top CLIP segment monitors the internal signal clipping. Itoperates independently of the rest of the meter, illuminating if signal clipping is

detected at any stage in the processing circuits regardless of whether the level of the nal processed signal is above or below the compressor and/or

limiter thresholds. Hence, the audio engineer has full visibility of any internal signal clipping that may result in audio distortion.

The 0 dB to – 40 dB signal meter is primarily designed to monitor the output level with respect to excessive levels that may cause damage to

the onward loudspeaker equipment. To do this it uses a dual-purpose scale that refers the signal level to both limiter threshold and compressor

threshold, as illustrated and described overleaf.

(1) The meter uses a downward relative scale where the “0” segment represents

the limiter threshold. For example, if the limiter threshold is set to +5 dB in

the output menu page, then the signal meter “0” segment represents 5dBu

true value, the –3 segment becomes 2 dBu down, -6 becomes -1 dBu down

and so on.

The compressor threshold is also marked, relative to the limiter threshold,

by a single steadily lit segment. For example, when the limiter threshold is

set to 8 dBu, the “0” segment is 8 dBu; if the compressor threshold is –1 dBu,

segment “9” will be illuminated.

Note If the limiter is set to OFF, the meter is scaled relative to21dBu.

(2) While the signal level lies below the compressor threshold, the meter

illuimates upwards from –40, such that the current headroom to both the

compressor and limiter thresholds can be monitored.

(3) When the signal level reaches the compressor threshold level, the meter

‘ips’ and reads downwards to show the amount of gain reduction applied

to the signal.

(4) With further increase, the meter reads in both directions, that is, it

increments upwards to track the signal level as it approaches the limiter

threshold and increments downwards to show the applied gain reduction.

(5) When the limiter kicks in, the meter ips to read downwards from the “0”

segment instead of just from the compressor threshold. It now shows the

summed gain reduction from both compressor and limiter.

6.4 Output Gain and Mute - Front Panel Control

Each output is equipped with a dual-action rotary/push-switch control for

adjusting or muting the output level. Note that zero mark on the control refers

to the baseline output level set in the Output menu (see Section 6.2.3) and hence

the rotary control provides ne-tuning relative to this level.

To increase/decrease the level turn clockwise/anti-clockwise

To mute an output push in and hold until the red ring

illuminates To un-mute an output push in

and hold until the red ring light extinguishes

To mute all outputs push in and hold an unlit output until it and

then all other controls illuminate

To un-mute all outputs push in and hold a muted (illuminated)

output until it and then all other red

ringsextinguish

7.3 Gang Mode Setup (Page 2)

This option is used to link multiple input channels or output channels together

so that a change on one channel will be made to all channels in the gang.

When a gang is created, the settings from the source channel are copied

to the destination channel(s) so that all ganged channels inherit the same

parameter values. From hereon, any changes to a ganged channel are carried

out on the other channels on an absolute basis, with the exception of input and

outputnames.

Notes A channel may only be part of one gang.

Only channels of a similar type may be ganged, that is, you cannot gang

input channels to output channels or vice versa.

Ganging is a feature of stand alone unit operation only and is not

compatible with the grouping facility oered in the Elgar 9848E Remote

Control Software add-in. Therefore, ganging is only active when the unit

is put into Gang mode, see Section 7.2; channel ganging is disabled if the

unit is set to receive data on a remote comms channel.

7.5 Analogue/Digital Input Select (Page 5)

This page selects the input source for input channels A and B, and C and D on a

paired basis due to the sharing of channels for AES/EBU inputs. There are three

options available for each input pair:

• • ‘Analog’ - switches to analogue inputs. Note that this is the default setting.

• • ‘DigSRC’ – switches to the digital AES/EBU input. In this mode, the unit locks

to its internal 48kHz clock reference. Sample rate converters (SRCs) support

incoming signals at sampling frequencies from 32kHz to 96kHz ± 12.5%.

• • ‘DigLock’ – switches to the digital AES/EBU input without sample rate

conversion. In this mode, the sample rate converter (SRC) of the digital input

is bypassed and the clock reference is set to lock to the channel’s incoming

AES/EBU bit stream. This allows the unit to be used in 48kHz systems

without incurring the propagation delay inherent in sample rate conversion.

Note If both input pairs are set to ‘DigLock’, then either pair may be selected as

the clock reference.

Any combination of analogue and digital inputs may be selected. For example,

input channels A and B may be set for analogue sources while input channels C

and D are digital.

• • To select the input source

1. Step through the Set Up menu to the Input Source select page.

2. Use the left DATA ENTRY control knob to select the input source for

channels A and B as shown opposite.

3. Use the centre DATA ENTRY control knob to select the input source for
